A short example about how to use traefik.
This example includes a configuration file called traefik.toml, where a network is declared which is used by traefik. In my case this network is called "traefik-global-proxy", which has to be created before startup, i.e.
docker network create traefik-global-proxy.
Afterwards, simply run the included docker-compose file
docker-compose up -d.
Now, check if traefik is running properly, by visiting traefik's dashboard at test.localhost.
